Specification of Letters Patent.

Patented Nov. 12,1907.

Application filed March l2. 1907.y Serial No. 36L934.

To all whomit may concern:

Be it known that we, GEORGE H. GooDrroLM and JACOB A. TRAIN, citizens ofthe United States, and residents of Lindsborg, in the county ofMcPherson and State of Kansas, have invented a new and Improved Tool, ofWhich the following is afull, clear, and exact description. Y

The invention has reference to improvements in tools for' cutting pipesand rods, in addition to splicing wir'e,

being more especially directed to the cutting of porcelain and otherbrittle tubes such as are used for insulating purposes.

The invention has for' its objects, among others, the provision oi meansfor the uniform cutting of tubes which may or may not be of exactcylindrical cross section, and for a novel pivotal adjustment for theoperating levers. 'l

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the igures.

Figure 1 is a side elevation of the tool with the levers locked; Fig. .2is a longitudinal, vertical section of the same taken substantially onthe line 2.-2 of Fig. 3; Fig. 3 is a plan of the outer portion of thetool; Fig. 4 is an inverted plan of an operating lever; Fig. 5 is airont end view of the tool; Fig. G is an inside end view of one of thecutting blades, and Fig. 7 is a like view of the opposite cutting blade.

The tool as preferably constructed,- comprises hand levers 1 and 2, madeof sheet metal by bending the same upon itseli leaving the opposed inneredges of the handle open, as is usual in plier construction. The leverll is extended at its forward end to provide a head 3, the Walls of saidhead being slightly separated to provide a longitudinal slot 4, in theouter end of which is pivotally mounted as on a screw or pin 5, acutting blade G. The top of the slot 4 is closed at the outer end of thetool, as best shown in Figs. 3 and 5, by bending the opposed Walls ofthe head inwardly, as indicated at 7.

Slidable Within the slot 4 at the rear of the blade 6, is a cuttingblade 8, both of said blades having V-shaped opposed cutting edges 9forming a diamond-shaped opening therebetween which is located oppositeto large elliptical openings 10 formed in the walls of the head 3, theselatter openings providing access of a tube, rod or the like between thecutting blades. As shown in Figs. 2, 6 and 7 the cutting edges 9 of theblades are beveled in the same direction, bringing them adjacent to oneWall of the slot 4 and in the same plane. This construction admits ofthe point at which the tube or rod is to be cut, to be accurately placedbetween the blades. The cutting edges of the blades by this arrangementwill also remain in the same plane even although they beinaceuratelyground. The cutting blade 6, as observed in Figs. 2' and 5, is madesomewhat shorter than the blade 8 and slot 4, permitting it to have alimited movement on its pivot 5. IThis leaves thc blade 6 free to rockwhen a tube er rod of/,inexact cylindrical cross section is being cut,whereby thecutting action takes place uniformly about its circumference.

For forcibly sliding the cutting blade 8 in the direction of the blade6, the lever 2 is flattened at its iorward end to lit the slot 4, andconstructed with a cam 11, which is formed of a double thickness ofmetal, as clearly shown in Fig. 4. Fixed to this end of the lever 2 justabove the cam 11,' is a pivot-pin 12 projecting at opposite sides, whereit is flattened on each side in a vertical direction when the lever isdisposed horizontally. This pin is adapted to [it in any one of a seriesof communicating openings 13 formed in the walls of the head 3, thecommunicating portions of said openings being in the nature of slots 14,which are of a width equal to the short diameter of the pin 12. Thisconstruction adapts the pivotal connection between the levers to be4shifted by swinging the lever 2 to a substantially vertical position,Where it is stopped by the rear ends of the portions 7 and sliding thepivot 12 to the required opening.

The levers 1 and 2 at the rear of their pivotal connection are formedwith a number of opposed cross grooves l5 of successive varyingdiameter, which are designed to splice wires as well known in the art.The lever 2 is also formed adjacent to the grooves 15, with a shearingedge 16 which coacts with a notch 17 formed in the lever 1 for cuttingwire and other like material.

For locking the levers together during the cutting action of the bladesG and 8, is provided at the rear end of the tool, a loop 18, said loopbeing swingingly connected to the lever 1 and adapted to engage with theextremity of the lever' 2 when the levers are forced together, a notchbeing preferably cut in the upper' face of the lever 2 for this purpose.

Itis obvious that various immaterial changes may be made in theconstruction of the tool irorn that hereinbefore described, and weconsider' that we are entitled to such m'odifications of the same asfall within the scope of the annexed claims.

Having thus described our invention we claim as new and desire to secureby Letters Patent:

.1.In'a tool of the character' described, cutting blades having opposedcutting.r edges, means providing for a limited pivotal movement of oneof said blades, and a hand lever operable to force the other bladetoward the pivoted blade. i

2. ln a tool ot the character described, cutting blades arranged in thesame plane havingr opposed V-shapcd cut-' head, 'seohd blade opposed tothe lrs't slidable within the slot of the head,.and a sheet ne'tl leverhaving a cani pivoted in the slot of said head operable to force saidslidable blade toward the other blade.

4, In a tool of the character described, a lever having a slotted head,a cutting blade pivoted in the slot of said head, 'a second cuttingblade opposed to the rst and slidable within the slot of said head, anda second lever pivoted to the head and having a cam projecting in theslot thereof operable to force said second cutting blade toward thepivoted blade.

In a tool of the character described, a lever having a slotted head, acutting blade pivoted in the slot 0f said head, a second cutting bladeopposed to the first and slidable within the slot of said head, a secondlever pivoted to the head and having a cam projecting in the slotthereof operable to foie said second cutting blade toward the' pi'v otedblade, and means for locking the levers together.

6. In a tool of the' character described, a lever having a slotted headconstructed of sheet metal, a cutting blade pivoted Within the slot ofthe head, a second blade opposed to the first slidable Within the slotof said head, and a sheet metal lever having a cam pivoted to said headand operable to force said slidable blade toward the pivoted blade.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing Witnesses.
